Windows 7 - Cannot logon because of logon method

I have a Windows 7 Pro computer on a domain suddenly giving this error when trying to login as admin or any user on the system:

"You cannot log on because the logon method you are using is not allowed on this computer"

Since I can't logon locally I edited the domain group policy to allow anyone to logon to all machines. That made the error go away, but now the machine either logs back off immediately or goes to a black screen and sits there where I can’t do anything including bring up the task manager. Safe mode does the same thing.

This computer is less than a month old and I we had no signs of malware (other than this perhaps)

Any ideas of what can be happening?

If it's doing it in safe mode and no other clients in the same OU are having the same problem I would just reimage the client machine. It sounds like something is very wrong with this machines OS.

Thats what I'm thinking. Unfortunatly the machine is about an hour away and it belongs to a CEO who can't really understand why his new computer is doing this. So I have been hoping to fix the issue instead of rebuilding from scratch.

move the pc to its own OU in AD.  make a group policy just for that out with the following settings.

Computer Configuration\Policies\security settings\user rights assignment
Double Click on Allow log on locally
Ensure that "Allow log on locally" includes Administrators, Backup Operators, Domain Users or Users.

that may get you in to check the settings of the local group policy and make any needed changes.

Did the CEO think it would be cool to enable his fingerprint reader?

The group policy is actually what I did. That allowed me to login, but after login we were getting a black screen or just bounce back to the login sceen.

Thanks!

Sounds like you might have malware or a virus like a rootkit causing problems. Try downloading and running TDSSKiller and run it on there in Safe mode. You may also want to look at this thread:

Let me get this straight. You are no longer getting the error "You cannot log on because the logon method you are using is not allowed on this computer" anymore now that you have changed the group security policy to allow local login, but now you are being auto-signed out?

Check to make sure there not a GPO for auto-logoff in GPO
Computer configuration->windows settings->security settings->local policy-> Then check to see if you have these options running.

auto logoff user when logon time expires
auto logoff user when logon time expires (local)


Also you may have SteadyState Installed and configured to Auto-logoff idle users. You might want to look into that as well. This certainly does not sound like a Malware case. Sounds like someone was messing with the policy's though.

Might I suggest you make a new roaming profile next time and see if that fixes the problem. Roaming profiles get corrupted quite often. Glad to see your problem was is gone now though. If you had responded earlier I could have suggested the roaming profile check before reimaging. Since reimaging is a last resort.

Thanks, interesting idea. Sorry this all went down pretty fast. By the time of your original reply we had already rebuilt the machine. Just now getting back to updating and closing the question.
